K&N WRENCH OFF® POWERSPORTS PERFORMANCE OIL FILTER

To satisfy the demands of racers, K&N oil filters has many features over and above the requirements of most vehicles. They use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The durable construction will withstand higher oil pressures found only in racing environments without bursting. The drilled hole on the nut is for a safety wire attachment. This is required for many types of racing, the safety wire prevents blown oil filters from falling on the track and representing a hazard to other race vehicles. This extra engineering offers peace of mind for consumers who want only the best.

K&N Premium Wrench-Off® Oil Filters

We have all been there: Whether it’s remembering where that disappearing oil filter tool is; or having oil leak all over your garage and yourself; or finally giving up and pounding a screwdriver through the filter just to get if off. Most of our canister type automotive and marine oil filters come with a 1” nut welded to the top of the canister so they can be easily wrenched-off with a standard tool. Most K&N canister type motorcycle and ATV oil filters come with a 17 mm nut.

Internally lubricated gasket provides positive seal while allowing easy on and off of filter

Rolled threads provide extra protection against stripping

High-Flow Rate

K&N oil filters have filtering media that allows for higher flow rates while providing outstanding filtration. High filter flow rates are important in racing vehicles where heavier grade oil is used and the oil is pumped much faster than in a standard vehicle. When the engine is circulating oil at high GPM rates, the high-flow oil filter helps reduce the loss of pressure through the filtering process.

Tech Talk

K&N Performance Gold Oil Filters use a cellulose media bound by phenolic resin surrounding a metal inner core that provides structural strength to reduce the risk of filter collapse. The resin is the "glue" that holds the media fibers together and at the same time keeps "pores" open by keeping the fibers apart. The resin is cured to full strength during the element manufacturing process. Phenolic resin systems are an excellent choice for the high temperature demands of oil filters.

K&N filters include an anti-drainback valve, when applicable, that prevents oil from draining back into the crankcase during engine shutdown. The anti-drainback valve is useful in situations where the filter is mounted horizontally which could allow backflow. K&N use rolled threads to help prevent stripping during installation or removal and an internally lubricated gasket provides a positive seal even after the filter has been removed and reinstalled.
